Symfony路由未找到但存在于调试器路由结果中

I generated a bundle but I receive error trying to access url http://localhost/app_dev.php/event:

No route found for "GET /event"

then I debugged the router with debug:router, and the router seems to be fine:

event_homepage             ANY        ANY      ANY    

/hello/{firstName}/{count}         
event_index                GET        ANY      ANY    /event/                            
event_show                 GET        ANY      ANY    /event/{id}/show                   
event_new                  GET|POST   ANY      ANY    /event/new                         
event_edit                 GET|POST   ANY      ANY    /event/{id}/edit                   
event_delete               DELETE     ANY      ANY    /event/{id}/delete        

after I have created the bundle automatically I had this error:

[ERROR] The bundle's "Resources/config/routing.yml" file cannot be imp
orted
from "app/config/routing.yml" because the "EventBundle" bundle is
already imported. Make sure you are not using two different
configuration/routing formats in the same bundle because it won't work

Below is all the routing structure files:

/home/stefano/starwarsevents/app/config/routing.yml

event:
resource: "@EventBundle/Resources/config/routing.yml"
prefix:   /

/home/stefano/starwarsevents/src/EventBundle/Resources/config/routing.yml

event_homepage:
path:     /hello/{firstName}/{count}
defaults: { _controller: EventBundle:Default:index }

event_event:
resource: "@EventBundle/Resources/config/routing/event.yml"
prefix:   /event

/home/stefano/starwarsevents/src/EventBundle/Resources/config/routing/event.yml

event_index:
path:     /
defaults: { _controller: "EventBundle:Event:index" }
methods:  GET

event_show:
path:     /{id}/show
defaults: { _controller: "EventBundle:Event:show" }
methods:  GET

event_new:
path:     /new
defaults: { _controller: "EventBundle:Event:new" }
methods:  [GET, POST]

event_edit:
path:     /{id}/edit
defaults: { _controller: "EventBundle:Event:edit" }
methods:  [GET, POST]

event_delete:
path:     /{id}/delete
defaults: { _controller: "EventBundle:Event:delete" }
methods:  DELETE

Slashes are counted and required. To help with this, I've put this RedirectingController in my codebase as a (nearly) final route, to catch and redirect to the slash-less version, should it happen.

But in the meantime the URL is currently /event/, not /event. You could also put the alternate one in as an alternate route to the same place.
